Maintenance For Tires
Explosive separation of a tire and/or rim parts can cause serious injury or death. Always follow the recommendations of the manufacturer or refer to the tire supplier.Always maintain the correct tire pressure. Inflate the tires according to the instructions from the tire manufacturer. Do not inflate the tires above the tire pressure that is recommended by the manufacturer.Inspect the tires and wheels prior to moving the trailer package. Do not tow the package if the following conditions exist:
The tire pressure is too high.
The tire pressure is too low.
A tire has cuts or bubbles.
A tire has excessive wear.
The rims are damaged.
Lug bolts or nuts are missing.Maintain the proper torque on the lug nuts of the wheels.Tire pressure will rise during towing and is a normal condition and tire pressure should not be reduced. High speeds during transporting may produce excessive tire pressures due to heat. Never purge the air from the tires. The tires can be cooled by REDUCING THE TOWING SPEED of the package or by stopping the package.Adjust the tire pressure from a distance. Use a long hose with a self-attaching chuck. Always stand behind the tread when you adjust the tire pressure.Do not inflate the tires with flammable gases or from systems that utilize an alcohol injector.Maintenance For The Running Gear
Refer to "Dexter AxleTrailer Running Gear Operation, Maintenance, Service : Form MM-2" for detailed information about the running gear, the brakes, the wheels, the suspension, the hubs, and the bearings.Inspect the wheel bearings. Check the lubrication level of the wheel bearings. Fill the wheel bearings only with Multipurpose Lithium Complex Grease (MPGL). Do not overfill the wheel bearings.Inspect the running gear for damage and wear.

Check the battery for the breakaway switch and ensure that the battery is properly charged. Check the battery charger that charges the battery for the breakaway switch. The battery charger should output 5 A at 12 VDC.After each rental period, inspect all the wiring connections for damage and/or wear. Make repairs to the wiring connections, as needed.Inspect the safety chains before you tow the trailer package.Check all of the fasteners for the proper torque prior to renting the package. Check the coupler attachment bolts. Check the bolts that attach the enclosure to the running gear of the trailer. Refer to the torque specifications within this manual for the proper torque for the bolts.
